BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant, botanically known as Calibrachoa parviflora andhereinafter referred to by the name ‘Docaltitor50’.

The new Calibrachoa plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new freely branching and early-floweringCalibrachoa plants with numerous large and attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made bythe Inventor in July, 2019 in Rheinberg, Germany of a proprietaryselection of Calibrachoa parviflora identified as code numberAA17-089063-001, not patented, as the female, or seed, parent with aproprietary selection of Calibrachoa parviflora identified as codenumber AA17-088072-001, not patented, as the male, or pollen, parent.The new Calibrachoa plant was discovered and selected by the Inventor asa single flowering plant from within the progeny of the statedcross-pollination in a controlled greenhouse environment in Rheinberg,Germany in May, 2020.

Asexual reproduction of the new Calibrachoa plant by vegetative terminalcuttings in a controlled greenhouse environment in Rheinberg, Germanysince June, 2020 has shown that the unique features of this newCalibrachoa plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Docaltitor50’. These characteristicsin combination distinguish ‘Docaltitor50’ as a new and distinctCalibrachoa plant:

-   -   1. Outwardly spreading, trailing and decumbent plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Large flowers with purplish red-colored petals with dark        red-colored centers and venation and vivid yellow-colored        throats and central star.    -   6. Good garden performance.

The new Calibrachoa can be compared to plants of the female parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe female parent selection in flower color as flowers of plants of thenew Calibrachoa are purplish red in color whereas flowers of plants ofthe female parent selection are light pink in color. In addition, plantsof the new Calibrachoa are more vigorous than plants of the femaleparent selection.

The new Calibrachoa can be compared to plants of the male parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe male parent selection in flower color as flowers of plants of thenew Calibrachoa are lighter purplish red in color than flowers of plantsof the male parent selection.

The new Calibrachoa can be compared to plants of Calibrachoa parviflora‘Docaltitogra’, disclosed in a U.S. Plant Patent application filedconcurrently. Plants of the new Calibrachoa differ primarily from plantsof ‘Docaltitogra’ in flower color as flowers of plants of the newCalibrachoa are purplish red in color whereas flowers of plants of‘Docaltitogra’ are purple in color.

Plants of the new Calibrachoa can also be compared to plants ofCalibrachoa sp. ‘USCAL91001’, disclosed in U.S. Plant Pat. No. 23,232.In side-by-side comparisons, plants of the new Calibrachoa differprimarily from plants of ‘USCAL91001’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more freely branching than        plants of ‘USCAL91001’.    -   2. Plants of the new Calibrachoa have longer and narrower leaves        than plants of ‘USCAL91001’.    -   3. Plants of the new Calibrachoa have larger flowers than plants        of ‘USCAL91001’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Calibrachoa plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Calibrachoa plant.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the spring and early summer in22-cm containers in a glass-covered greenhouse in Rheinberg, Germany andunder cultural practices typical of commercial Calibrachoa production.During the production of the plants, day and night temperatures averaged18° C. and light levels averaged 4,500 lux. Rooted young plants werepinched one time three weeks after planting. Plants were twelve weeksold when the photograph was taken and 25 weeks old when the descriptionwas taken. In the following description, color references are made toThe Royal Horticultural Society Colour Chart, Fifth Edition, 2007,except where general terms of ordinary dictionary significance are used.
